Why would we be talking about JUST the here and now? It's useless idle chitchat because there is about zero probability war would start this year, or even next. On the other hand, the probability of a "mistake" probably grows higher as time passes into the 3-5 year period and beyond.
People with short term memory may look only at the here and now and get lost when tomorrow comes (hello GM), but to be truly effective one must look at current trends and extrapolate to future potential situations. It always amazes me to think that in the 1960s Japan was mocked as the manufacturer of cheap and shoddy goods, and a short 2-3 decades later were bringing detroit to its knees. Sound familiar?
If you've ever been to China, as I have, you would be amazed at the extremely rapid modernization going on over there. Less than 10 years ago, bicycles filled the streets of its main cities and cars were scarce, but now China is the largest car market in the world and BMWs, Mercedes, land cruisers, and various models and makes clog its roads - while skyscrapers grow like flowers (Shanghai has the best skyline in the world probably) and maglev trains zip along at incredible speeds. China's per capita income is 108 times higher today than it was in 1949 when the Communists took over. To put that into perspective, it took Great Britain almost the entire 9th century to raise its per capita income 2.5 times, 60 years to raise its per capita income 3.5 times in the U.S. from 1870 to 1930, and Japan took 25 years, from 1950 to 1975, to increase its per capita income 6 times.
It would be a major mistake to just focus on the here and now and be blind to the fact that China is modernizing and expanding at a rate that is probably unprecedented in human history.
To get back to the subject, as I said, the days of lumbering Carrier fleets are probably over (at least against major powers with ballistic and space capabilities) as the major powers gain ever more accurate ballistic missile technologies and the surrounding space infrastructure to direct those missiles - just as the days of battleships ended with the coming use of deadlier warplanes.
